TYPE-BAR-SUPPORTING RlNG AND HANGER FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part-of Letters Patent No. 767,946, dated August 16. 1904. Application filed February 1 6, 1904. Serial No. 193,783. (No model.)

To all whom it natty concern:

Be it known that I, GEORGE M. KITZMILLER', a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Type-Bar-Supporting Rings and Hangers for ype-Writing Machines; and I declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains-to make and use the same.

My invention has for its object to provide a means of support for the type-bars and also certain guides, buffers, or cushions, as will be hereinafter described- Referring to the drawings, Figure 1 is a front view of'the supporting-ring, hangers, and universal guide. Fig. 2 shows the out-- line of the dovetails or angular slots, taken on a view looking downward upon Fig. 1, the ends of the slots only being shown in outline. Fig. 3 is an enlarged view in elevation of the type-bar buffer or cushion, showing also the curved universal guide; and Fig. 4 is a part top plan of the same. Fig. 5 isa plan of the type-bar hangers or fulcrum-blocks Fig. 6 is an elevation of the type-bar hangers, showing a connection to the key-lever. Fig. 7 is a front view of the type-bar hanger with a part of the type-bar-supporting ring, as is also shown in Figs. 5 and 6. R

In the drawings like figures of reference in.- dicate corresponding parts in all the views.

1 is a movable support attached to the ma chine in such a manner that it can be raised or lowered for printing upper and lower case, as is ordinarily done.

2 is a cross or universal guide-bar fastened at each end of the frame 1, as at 3. This bar is also fastened to each end of the type-barsupporting ring 22 by a dovetailed joint 5. The joint is secured in place and prevented from having lost motion 'by means of the screws 6. The universal guide-bar 2 is in two parts, being separated at its middle, and upon the ends there is placed curved guides 7. (Shown more plainly in Fig. 4.) The opening between the guides 7 is slightly larger bar when in the slots is shown than the type-bars 25 and acts as guides for same, so that they may strike in perfect alinement upon the platen. The position of the in Fig. 1 by the dotted lines 25. The universal bar 2 is supportedby the curved arms or braces 8,

fastened to the guide-bar 2 at 9 and upon the ring 22 at 10.

11 represents dovetailed or angular slots placed, radially in the ring 22, so as to receive corresponding lugs upon the backs of the type-bar hangers 13, which are held in place by means of the screws or pins 14. v

15 represents guides or shoulders on the type-bar hangers 13, so that the type-bars'will be moved without lost motion or side play.

16 is a buffer-plate placed over the opening between the universal guides 7. (Shown on a larger scale in plan in Fig. 4.) The plate 16 has guide-rods 17 passing through the guides 7. The object of the plate 16 is for the purpose of preventing the vibration of the typebars when they have struck the platen, the recoil being taken up by the springs 19, which are compressed when the type-bars strike the platen, and by its extension causes the typebar tobe quickly withdrawn, during which operation the buffer or cushion plate 16 takes the position shown approximately by the dotted lines'18.

20 indicates the opening in the guide-bar 2 between the guides 7 for the passage of the type-bar 25.

21 indicates apertures between the bufferplate 16 andthe guide-bar 2 for supporting a suitable shaft for the ribbon-lift, which does not form a part of my present invention, and hence is not further shown and described.

22 is the type-bar-suppOrting ring, carrying the hangers 13. The ring has suitable dovetailed slots and holes, as shown at 11 and 12, respectively, forming means for attachment for the hangers 13, as already described.

23 is a dovetailed lug to fit in a correspondingly-shaped opening, as at 11, Figs. 1 and 2.

25-indicates the type-bars, fulcrumed in the hangers 13 by the screw or pin 26.

27 is an arm of the type-bar, connected by means of a twisted link 29 and is in turn connected by certain intermediate levers to the key-lever by which the machine is operated; but these are not described in detail, as they form a basis for a separate application previously filed by me covering such improvements, though for illustration I show a bellcrank 31, fulcrumed at 33 and connected to the twisted link 29 by the joint 30. The keylever is connected to the bell-crank 31 by the link whose joints are shown at 3a and 35, respectively. The key-lever is fastened to a suitable part of the frame of the machine, as at 38, by the joint or fulcrum 89. The typebar hangers 13, located on the ring 22, have slots for two type-bars, though I am not confined to that number, as in special cases I may use one or three. The dovetailed joint, as at 23, Fig. 5, permits the several parts to be in serted from above and below, and when in the proper place they are fastened by means of the screws or pins 14:, which facilitates the renewal and replacing of the several parts without afiecting'the proper alinement of the machine. The hangers 13 have flat sides, so as to allow them to abut and form a continuous semicircle or circular row, the slots 11 and hangers 13'being' so arranged that they provide equal distances between the guide-slots .15, and consequently the type-bars. The entire ring, buffer, and hangers are vertically movable, so as to enable the type-bar to strike the platen in two or more places to efiect the change from lower to upper case, as is usual with shifting-key arrangements.

In Fig. 6 the position of the type-bar when at rest is shown at 25 by full lines and by dotted lines also shown at 25 when striking the platen or in its vertical position.

The rest of the elements constituting a complete type-writing machine not forming a basis for claims have been omitted in my invention.

I am not confined to the exact construction as shown in Fig. 1, as I may place the slots entirely or partly through the width of the ring, according to the conditions met with in constructing my machine, nor am I confined to the depth of the bolt 24 in the ring 22, as it may be through it or partly through the same, according to the thickness.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination of a movable type-barsupporting circular ring for type-writing machines, having a series of radial dovetailed slots in the said ring, a divided guidebar across the diameter of the type-bar-supporting ring, and curved arms or braces for securing the said divided guide-bar to the ring, as described.

2. The combination of a vieldably-supported semicircular type-bar-carrying ring,or basket, for type-writing machines, provided with dovetail slots on the said ring, and guide-bars on each end of the said ring, a curved arm or brace for supporting each section of the said bars on the ring, and curved upset ends on the divided portion of the said guide-bar for the passage of the type-bar and the guiding of the same upon the platen, as described.

3. The combination of a verticall'adjustable type-bar-supporting ring for type-writing machines, provided with a radially-angular slotted ring, a divided bar across the diameter of the ring, a curved brace for supporting the said divided bar, a curved head on the ends of the said bar at its divided portion, and. a spring-cushioned buifer or impact-plate at the divided portion of the guide-bars for absorbing the recoil of the type-bar after it strikes the platen, as described.

4. The combination of a shifting type-bar supporting semicircular ring, or basket, for type-writing machines, comprising a series of dovetailed slots, a dovetailed curved headed guide-bar on each end of the semicircular ring, and extending to the center, a curved brace, or arm, for securing the said bars to the ring, a spring-compressing buii'er-plate across the opening between the curved heads of the divided guide-bar for preventing vibration of the type-bar after it has struck the platen, and a pendent projecting dovetailed type-bar hanger, or block, the said block litting corresponding apertures in the said typebar-supporting ring, as described.

5. The combination of a type-bar-supporting ring for type-writing machines, provided with curved headed guide-bars extending to, or near the center of the said ring, the said bars being separated to form a gap or opening between them, a yieldably-supported buffer-plate across the said opening of the two adjacent guide-bars, a projecting curved slotted type-bar hangers or blocks, in the dovetailed opening on the said ring, means for fastening the said type-bar hangers in the circular apertures in the ring, and one or more ver tical slots in the said type-bar hanger, the said slots being provided with outwardly-cxtcnding shoulders or guides for the passage of the type-bars during their stroke, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

GEORGE M. KI ZMILLER.
